1 mass SpectroscopyMass Spectroscopy is a technique causing the formation of the gaseous ions with or without fragmentation; the gas phase ions are then characterized by their mass to charge ratios (m/z) and their relative MS, compounds are ionized. The ionized molecule often fragments into smaller ions/radicals. The positively charged fragments produced are separated based on their nominal_mass/charge (m/z) ion daughter ions, radicals, neutralsMost of the ions has z=+1, thus in a given ion, m/z = mass of the plot of relative abundance of ions vs m/z of all charged particles is the mass fragmentationM M+.M+1+ M+.2+..+N1+ N2. + .. If the quantity of energy supplied to a molecule is greater than it s ionization energy a molecular ion is formed (parent ion).The mass spectral pattern is unique to a molecule(fingerprint), especially massMolecularion M+.Molecularion M+.++Base peakv. stable ionDaughter ionsFree radicalsneutralsMass Spectrum presented as a bar Peak M+.
